| Electrochemicals granted Patent |
|
October 2, 2002The Patent and Trademark Office (PTO) of the United States has granted another patent related to Electrochemicals' SHADOW® Direct Metalization Process.The invention, "Aqueous Carbon Composition and Method for Coating a Non Conductive Substrate," is U.S. Patent number 6,440,331. The invention describes a composition and method for applying an electrically conductive coating to a non-conductive substrate such as a printed wiring board, organic chip carrier or a plastic. |
The process is designed to apply a conductive carbon coating in combination with an additional conductive material. The resulting coating has improved conductivity over prior through-hole coating compositions and processes, and enables the electro-deposition of copper for increasingly complex electronic interconnect devices. The inventors are Michael Carano and Frank Polakovic. Frank recently retired from the company. |
